此文为mysql 服务器安装脚本。

#!/bin/bash

#ver 0.2

#by zm 2011/04/23

#安装 mysql_server;

#注意！！

#参数解释

#

# CFLAGS="-O3" CXX=gcc CXXFLAGS="-O3 -felide-constructors \

# -fno-exceptions -fno-rtti -fomit-frame-pointer -ffixed-ebp" // 如果是Inter处理器，使用pgcc提高1%性能

#

#

# --with-unix-socket-path=/usr/local/mysql/tmp/mysql.sock // 使用unix套接字链接提高7.5%性能，所以在windows下mysql性能肯定不如unix下面

# --with-client-ldflags=-all-static

# --with-mysqld-ldflags=-all-static //-static 13%,静态链接提高13%性能

#

# --with-readline 从“行”上面读取

#

# --with-charset=utf8 指定缺省字符集

#

# --with-collation=utf8_general_ci 指定缺省排序方式

#

# --with-extra-charsets=complex 安装所有字符，有这个就足够了

#

# --with-extra-charsets=all 指定安装扩展字符集

#

# --enable-local-infile 指定允许本地导入文件

#

# --enable-thread-safe-client 指定线程安全模式

#

# --enable-assembler 允许使用汇编模式(优化性能)

#

# --with-big-tables 指定支持超大表

#

# --without-debug 去除诊断模式，如果用--with-debug=full编译，大多数查询慢20%

#
